41Coherent risk measure — In the field of financial economics there are a number of ways that risk can be defined; to clarify the concept theoreticians have described a number of properties that a risk measure might or might not have. A coherent risk measure is a function …
42Coherent topology — In topology, a coherent topology is one that is uniquely determined by a family of subspaces. Loosely speaking, a topological space is coherent with a family of subspaces if it is a topological union of those subspaces. Contents 1 Definition 2… …
43Coherent diffraction imaging — A diffraction pattern of a gold nanocrystal formed from using a nano area beam of coherent X rays. This reciprocal space diffraction image was taken by Ian Robinson s Group to be used in the reconstruction of a real space coherent x ray… …

45Coherent backscattering — In physics, coherent backscattering is observed when coherent radiation (such as a laser beam) propagates through a medium which has a large number of scattering centers (such as milk or a thick cloud) of size comparable to the wavelength of the… …
46Coherent space — In proof theory, a coherent space is a concept introduced in the semantic study of linear logic. Let a set C be given. Two subsets S,T ⊆ C are said to be orthogonal, written S ⊥ T, if S ∩ T is ∅ or a singleton. For a family of C sets (i.e., F ⊆… …
47Coherent duality — In mathematics, coherent duality is any of a number of generalisations of Serre duality, applying to coherent sheaves, in algebraic geometry and complex manifold theory, as well as some aspects of commutative algebra that are part of the local… …
48Coherent ring — In mathematics, a (left) coherent ring is a ring in which every finitely generated left ideal is finitely presented. Many theorems about finitely generated modules over Noetherian rings can be extended to finitely presented modules over coherent… …
49Coherent spectroscopy — Spectroscopy is the study of light through light matter interactions. There are three main types of interactions: Quantized interactions in which involved molecules (Here: atoms, full or parts of molecules or crystals,..) jump from a stationary… …
50Coherent sampling — Fast Fourier Transform (FFT) is a common tool to investigate performance of for data converters and other sampled systems. Coherent sampling refers to a certain relationship between input frequency, fin, sampling frequency, fs, number of cycles,… …
